Help Support This Theme

2014-09-02: Hi everyone. Big changes in the software world, and I'm going to need your help to get the new software *and hardware* needed to keep developing this theme. See the details here, or just make a contribution right here and now on this page. It matters, and your support makes it possible. Thank you!

Welcome

This theme is for people who like it dark. If you're running a dark desktop, browsing at night, or just looking for a change, this is for you.

You can use this theme two ways:

1 - as a simple dark theme with a dark toolbar, which is how it is installed by default2 - with your choice of NASA toolbar images, which you enable with a couple extra steps (see below)

- Extension compatibility: compatible with a long list of Firefox extensions, including many of the most popular.- Customization: add NASA background images and fine-tune the look of your toolbar. See the whole list.- Desktop Integration: looks great on its own (for Windows XP, Vista, Windows 7, OS X, and Linux) and with dark desktop themes, including Zune, Royale Noir and Silent Night.

Limitations

Every system has its limits. Here's ours.

- Some extensions need custom handling which we don't yet provide. Feel free to suggest enhancements on the NNL support forum.- It's bigger than most themes because of the background images. (There's around 1MB of NASA images in the theme. This is simpler for people than having to download them separately.)- Does not fully support Firefox in RTL (right-to-left) mode.- Does not fully support OS X Retina High-DPI displays. The icons may be fuzzy, so just switch back to the Firefox default theme in that case.
